Ushbu ilmiy maqolada raqamli dastur bilan boshqariladigan (CNC) vertikal frezalash stanoglarining asosiy tarkibiy qismi bo‘lgan yuritmalar (drive systems) ning takomillashtirish yo‘llari kompleks tahlii qilinadi. Zamonaviy ishlab chiqarishning yuqori aniqlik, tezkorlik, samaradorlik va moslashuvchanlik talablari an'anaviy yuritma tizimlarining imkoniyatlari chegarasidan ancha tashqariga chiqqan. Tadqiqotning asosiy maqsadi vertikal frezalash stanoglarining yuritma tizimlarini yopiq halqali raqamli servo motorlar, to‘g‘ridan-to‘g‘ri haydash (direct-drive) texnologiyalari, aqlli boshqaruv algoritmlari va sanoat 4.0 tamoyillari asosida takomillashtirishning nazariy asoslarini va amaliy metodologiyasini ishlab chiqishdir. Maqolada dastgohning dinamik va statik tashqi yuklarga bardosh bera olish gobiliyatini (egiluvchanlik va tebranishlarning kamayishi) oshirish, energiya samaradorligini yaxshilash, o‘lchov aniqligini oshirish va tizimning diagnostika qilish gobiliyatini rivojlantirish yo‘nalishlari chuqur o‘rganilgan. Taklif etilgan yechimlar eksperimental sinovlar asosida tasdiqlangan bo‘lib, ular asbobning ishlash muddatini 25-30% ga oshirish, sirt pürüzlülüğü (Ra) parametrini 0,2 mkm gacha kamaytirish va energiya sarfini 15-20% ga qisqartirish imkonini beradi. Xulosa qilib aytganda, yuritmalarni takomillashtirish nafaqat yakka dastgohning ishlash ko‘rsatkichlarini oshiradi, balki butun ishlab chiqarish liniyasining raqamlashtirilishi va avtomatlashtirilishiga asos bo‘lib xizmat qiladi.
